SPAIN: A house has been hit by pieces of a turbine blade that fell from a 300kW turbine in Spain following high winds, several local press are reporting.

Two 15-metre blades from the turbine disintegrated in the early morning of 3 January, striking an occupied house 280-metres away.

The blade failure occurred on one of 61 Desa A300 turbines at the 18.3MW Corme wind plant in the Ponteceso district of Spain's northernmost province of Coruna.

The project is owned and operated by EDP Renovavais and has been online since 2000. Desa once belonged to Spanish turbine pioneer Abengoa and is now partly owned by EDP.

The owner of the house affected reported to local media that the turbine had been making "unbearable noises" for a few days before the incident, following high winds in the area.

On the eve of national holidays in Spain, EDP failed to comment to Windpower Monthly on the incident. But the company had issued a provisional statement to the local press saying it was "too early" to pinpoint the causes.

Its statement firmly denied that an explosion had occurred in the turbine, as reported by some local witnesses.

It also confirmed the turbine was operating at the time of the incident, as wind speeds at the time were within safe operational limits, at 90km/h (25m/s). Turbines had been halted in recent weeks due to higher winds, the statement said.
